Embodiment 1

[0029] A kind of preparation method of high-efficiency flame retardant and smoke suppressant for wood composite material of the present invention comprises the following steps:

[0030] 1) Synthesis and preparation of intumescent flame retardants. Add 73g of melamine, 16g of nitric acid and 500mL of deionized water into a 1000mL four-neck flask, gradually raise the temperature to 90°C under stirring, and slowly add 67.6g of sodium pyrophosphate after the melamine is dissolved. Continue to stir at 90-95°C, and pay attention to measuring the pH of the reaction solution. When the pH is ≥ 6.0, stop the reaction and obtain a white paste, which is washed and filtered several times, and then placed at 102±3 °C in a vacuum drying oven to constant weight, crushed and sieved to obtain a white powder, and the intumescent flame retardant melamine pyrophosphate was obtained with a yield of 89.6%.

[0031] 2) Synthesis and preparation of organic montmorillonite. Add 80.0g of montmorilloni...

Abstract

The invention discloses an efficient flame-retardant and smoke-suppressant agent for a wood-based composite material and a preparation method thereof. The efficient flame-retardant and smoke-suppressant agent is prepared from 55-65 parts of inrumescent flame retardant, 2-6 parts of organic montmorillonite, 15-25 parts of nano-metal hydroxide and 10-20 parts of magnesium sulfate whisker. The preparation method includes the following steps that 1, the inrumescent flame retardant is synthesized and prepared; 2, the organic montmorillonite is synthesized and prepared; 3, the nano-metal hydroxide and the magnesium sulfate whisker are prepared; 4, the efficient flame-retardant and smoke-suppressant agent is prepared. The adopted raw materials including the inrumescent flame retardant, the organic montmorillonite, the nano-metal hydroxide and the magnesium sulfate whisker achieve multiple synergistic flame-retardant effects including synergistic flame retardant of the inrumescent flame retardant and the organic montmorillonite (the inrumescent flame retardant-nano synergy) and synergistic flame retardant of the organic montmorillonite and the nano-metal hydroxide (nano-nano synergy); the advantages of being high in flame-retardant, environment-friendly and smoke-suppressant efficiency, low in smoke and poison and the like. The technology is simple, industrialization is easy, and cleanliness and non-pollution can be achieved.

Description

technical field [0001] The invention relates to the field of flame-retardant and smoke-suppressing agents for wood composite materials, in particular to a high-efficiency flame-retardant and smoke-suppressing agent for wood composite materials and a preparation method thereof. Background technique [0002] Wooden materials are favored by people for their unique material properties and excellent environmental characteristics, and are widely used for decoration in homes and public places. Wood material is a kind of natural renewable biomass material, and it is a kind of flammable material with fire hazard. Once a fire occurs, it will seriously threaten people's life and property safety. At the same time, in a fire, the smoke and poisonous gas released when the wood materials are burned are the main causes of casualties. For this reason, it has become the common pursuit of relevant technicians to develop wood products with high-efficiency flame-retardant and smoke-suppressin...
